99 yukon 5.7 misfire
I bought this yukon a few months ago,it had a miss but i didnt think it was nothing major since i bought it from a woman.I gave it a tune up,plugs,wires,distributor cap,and rotor bug.It still says number 5 misfire.I replaced the coil,and distributor.So maybe it was a fuel injector,i replaced the spider and nothing has changed,Now im stumped and dont know what to do,any suggestions?
